Sasuke is very likely to be involved. He has a close relationship with Naruto and is also an important figure in Boruto's life. His skills and knowledge could be crucial in any adventure or situation that Naruto and Boruto find themselves in. Another character could be Hinata. As Naruto's wife, she would surely be concerned about any strange events involving Naruto. And for Boruto, she is his mother, so she would play a role in any family - related or village - threatening situations.
The most popular characters in 'Boruto meets Naruto fanfiction' are Naruto and Boruto, as they are the main focus of the concept. However, characters like Jiraiya can also be very popular. His connection to Naruto and his own legendary status add depth to the fanfiction. Shikamaru is another character that fans like to see in these stories. His intelligence and laid - back attitude can create some interesting interactions with the main characters.
One possible interesting plot could be Naruto and Boruto getting transported to a parallel dimension where their roles are reversed. Boruto has to deal with the challenges Naruto faced in the past, like fighting powerful villains without the advanced technology he's used to. Meanwhile, Naruto gets to experience the modern ninja world from Boruto's perspective, including the new ninja tools and different social dynamics in the Hidden Leaf Village.
In a 'Boruto meets teen Naruto' fanfiction, Boruto could be amazed by his father's skills as a teen. He might see Naruto's determination in a new light and gain a deeper understanding of his own potential. Maybe they'd train together, with Naruto teaching Boruto some of his old - school jutsu.
In a fanfiction where Boruto meets Kid Naruto, there could be a lot of chaos at first. Boruto might be shocked to see a younger version of his father. Kid Naruto would probably be curious about Boruto's strange clothes and gadgets. They could end up getting into some kind of adventure together, like facing a common enemy. Maybe Boruto would show Kid Naruto some of his ninja techniques from the future, and Kid Naruto would teach Boruto some of his own unique skills that he developed during his own time as a young ninja.
In such a fanfiction, Naruto could share his old ninja tales with Boruto. Maybe he'd tell about his battles against the Akatsuki. Boruto would be in awe, seeing his father in a new light.
Well, in such a fanfiction, Boruto might be really shocked to see his father as a teenager. Maybe they'll have a sparring match where Teenage Naruto shows off his wild and unrefined yet powerful skills, and Boruto has to adapt to fighting this different version of his dad. They could also have some heart - to - heart talks about Naruto's dreams back then and how Boruto can better understand his own path.
One idea could be Boruto getting transported back in time and meeting a young Naruto. He could then help Naruto avoid some of the early hardships he faced, but also realizes that those hardships made Naruto who he is. Another could be Naruto and Boruto switching bodies for a day, which would lead to humorous situations as they try to navigate each other's lives. A third idea might be that Boruto discovers a hidden power within himself by training with Naruto in a special dimension where time moves differently.
One possible scenario in this fanfiction could be Jiraiya taking on the role of a mentor to young Naruto even more intensively. He might teach Naruto some unique jutsu that are not part of the original storyline. For example, he could introduce Naruto to some ancient toad - related techniques that are only known within the toad clan.
Definitely Naruto and Sasuke. In a 'past Naruto meets Boruto' fanfiction, if Sasuke was also involved in the meeting, it would be really cool. Boruto could see the dynamic between his father and Sasuke, two of the most powerful ninjas. He could learn about their past rivalries and how they overcame them to become allies. It would be a great opportunity for Boruto to understand the importance of having a strong bond with your comrades.
